Abstract:

A baby monitor system has a child unit with a child transducer that receives and converts incoming audio signals to an incoming analog signal. The child unit has an analog-to-digital converter that converts the incoming analog signal to outgoing digital data. A child unit microprocessor converts the outgoing digital data to a wireless signal and a transmitter of the child unit transmits the wireless signal. A parent unit has a receiver that receives the wireless signal and converts the wireless signal to incoming digital data. A parent unit microprocessor processes the incoming digital data. A digital-to-analog converter in the parent unit converts the processed incoming digital data to outgoing analog information. A parent unit transducer converts the outgoing analog information and transmits outgoing audio signals representative of the incoming audio signals.
